Co-op Study on Increasing Value Added to Agricultural Production -in Chiang Mai Province-

为了提高泰国清迈省的农业生产，我们通过大学与大学合作研究项目（国际科研计划）通过科研资助开展了以下五个课题。1994-1995年期间的项目成果如下：适合热带国家雨季蔬菜生产。建议采用高垄防雨栽培，避免土壤水分过多伤害。然而，在旱季，灌溉系统必须完全建立，以生产高质量的蔬菜。在清迈省周边地区，有必要加强抗病、抗虫、耐热和耐湿育种，以提高蔬菜的质量。热带地区的牲畜有偏瘦的趋势，这是由低营养饲料造成的。为了提高牲畜产量，需要有高饲用价值的优质饲料。资源开发是培育新型饲料作物的重要课题。豆科植物的杂草或灌木可能对这一目的有用。泰国人的需求正在转变为消费高质量的产品。为了保持农产品的新鲜，建议包装。这种处理可能会改变营销系统，销售和购物。泰国研究人员访问了种植高品质蔬菜的日本农民，该农场位于爱媛县最著名的生产地区。他们学会了如何控制温室环境，生产出优质的番茄果实“Momotarou”。他们还参观了自动操作水果分级机的包装厂。我们从两所大学分别派出并邀请了六名研究人员。他们都成功地交流了学术观点和合作实地研究。这次经历将有助于他们今后的研究。

To enhance the agicultural production in Chiang Mai province, Thailand, we carried out the following five subjects by the University-to-University Cooperative Research Project (International Scientific Research Program) through a Grant-in-Aid for Scientific Research.Results of the project during 1994-1995 were as follows ;1. For vegetable production in the rainy season of tropical country. high ridge and protected cultivation from rain are recommended to avoid excess soil moisture injury. However in the dry season, irrigation systems must be fully established to produce vegetables possessing high quality.2. At around Chiang Mai province, intensive breeding program for disease resistant, insect resistant, heat tolerant and wet endurant is necessary to improve the vegetable.3. Livestock in tropical area has a tendency to be thin, which is caused by low nutrient feeds. To increase livestock production, it requires good forages that having high feeding values. Exploitations of resources are most important theme to breed the new forage crops. Weeds or bushes belong to leguminosae might be useful for this purpose.4. Demands of Thai people are changing to consume high quality products. To keep agricultural products fresh, packing is recommended. This treatment may change the marketing systems, selling and shopping.5. Thai researchers visited Japanese farmers who grow high quality vegetables and it located in the most famous production area in Ehime prefecture. They learned how to control the greenhouse environment to produce fine tomato fruits "Momotarou". They also visited packing house in which fruits grading machines are automatically operated.We sent and invited six researchers each between two universities. All of them exchnged academic views and cooperative field research successfully. The experience will improve their future research.
